About this map

Alkali Springs Coulee and its neighboring drainages define the landscape of this high-plains region along the border of Liberty and Chouteau counties. The area is characterized by a network of seasonal watercourses, including Pondera Coulee and Carlson Coulee, which cut through the terrain to create distinctive geological features. This 2020 survey illustrates the section-line road system that organizes the modern agricultural and ranching life of the Montana plains.

Local transportation is facilitated by thoroughfares like Broadhurst Rd and Selma Rd, which connect remote homesteads across the townships. The boundary between Liberty County and Chouteau County is clearly delineated, showing how administrative lines intersect with the natural flow of Basin Coulee and other drainage basins. This map provides a clear record of the rural infrastructure and topography of the Northern Montana region in the early 21st century.
